【摘要】 在３８０ ～４６０ ℃，１ ～３ ｈ 条件下，在自制的热裂化反应实验装置上，对减压渣油重胶质进行了热反应，讨论了减压渣油重胶质热反应规律。实验数据表明，减压渣油重胶质在小于４００ ℃条件下，具有较强的转化能力，基本不生成焦炭；在大于等于４００ ℃条件下，明显有焦炭生成，并且随着反应温度提高，生成的焦炭及气体明显增加。减压渣油重胶质的热反应生焦特点是：初次反应的较低分子质量的产物中，高芳碳率的产物结合形成中间体产物，然后进一步缩合成焦炭。分析了减压渣油重胶质热反应生焦特征；描述了减压渣油重胶质的生焦机理更多还原

【Abstract】 Under conditions of reaction temperture 380～460℃ and reaction time 1～3 h, with home-made thermal cracking reaction experiment device, vacuum residue heavy resin thermal reaction was processed, and the reaction law has been discussed. The experiment data show, that under condition of reaction temperture <400℃, heavy resin is an intense to converson and not to be coke. Under condition of reaction temperture ≥400℃, the coke was produced. The coke and the gas obviously increased with thermal reaction temperture increasing. The characteristics of the coke produced of the heavy resin thermal reaction is that high aromaticity products form intermediate products and then condense to coke in low molecular weight products. The feature of the heavy resin thermal reaction and the mechanism of the heavy resin coke forming have been analysed and described.更多还原
